Measures of communication deviance derived from three different Rorschach situations were obtained from parents of 62 children vulnerable to future psychiatric disturbance. The families were maritally intact, with one parent having a history of previous psychiatric hospitalization and a male index child, 7 or 10 years of age. Amount of parental communication deviance in one situation was not significantly related to amount of communication deviance observed in another setting. However, mothers who exhibited high levels of communication deviance in both the Individual and Family Consensus situations tended to have offspring who were judged as low functioning in multiple settings, based on teacher ratings, peer ratings, and parental report. Conversely, children judged as high functioning in multiple settings had mothers who were free of high levels of communication deviance in both Rorschach situations.
